Drilling in Metal
A SDS PLUS to round shank adaptor chuck is required.
Ensure that tool is in Rotary Drilling mode. Start drilling with
slow speed and increase to full power while applying firm
pressure on the tool. A smooth even flow of metal chips
indicates the proper drilling rate. Use a cutting lubricant
when drilling metals. The exceptions are cast iron and brass
which should be drilled dry.
nOTE: Large (5/16" to 1/2" [7.9 mm to 12.7 mm]) holes
in steel can be made easier if a pilot hole (5/32" to 3/16"
[4 mm to 4.8 mm]) is drilled first.
Drilling in Wood
A SDS PLUS to round shank adaptor chuck is required.
Ensure that tool is in Rotary Drilling mode. Start drilling with
slow speed and increase to full power while applying firm
pressure on the tool. Holes in wood can be made with the
same twist drills used for metal. These bits may overheat
unless pulled out frequently to clear chips from the flutes.
For larger holes, use spade bits, power auger bits, or hole
saws. Work that is apt to splinter should be backed up with
a block of wood.
Drilling in Masonry
When drilling in masonry, use carbide-tipped bits rated for
percussion drilling and be certain that the bits are sharp.
Use a constant and firm force on the tool to drill most
effectively. A smooth, even flow of dust indicates the proper
drilling rate.
Recommendations for Tool Operation
When drilling, always apply pressure in a straight line
with the bit, but do not push hard enough to stall the
motor or deflect the bit. A smooth even flow of material
indicates the proper drilling rate.
